To solve the world's biggest problems, invest in women and girls | Musimbi Kanyoro

As CEO of the Global Fund for Women, Musimbi Kanyoro works to support women and their ideas so they can expand and grow. She introduces us to the Maragoli concept of "isirika" -- a pragmatic way of life that embraces the mutual responsibility to care for one another -- something she sees women practicing all over the world. And she calls for those who have more to give more to people working to improve their communities. "Imagine what it would look like if you embraced isirika and made it your default," Kanyoro says. "What could we achieve for each other? For humanity?" Let's find out -- together.
